I question the morality of any sport where the goal is to give one’s opponent a concussion, but some people have decided to give such a sport a new twist. Today’s weird thing is the World Chess Boxing Organisation, in which players alternate rounds of chess and boxing. Personally, I think this would be more interesting if they played chess while boxing. (Disturbing the board or hitting one’s opponent while making a move would probably be prohibited.) Enjoy, share the weirdness, and do not try this at home.
